## 【Abstract】

The Shimane University Industry-University Cooperation Center has been engaged in the research project as a team to apply “Japan’s production technology” to medical science. The medical department verified the effectiveness of "the bone screw made of the patient’s own bone", the department of science and engineering established its processing method, Nano Corporation manufactured a competent microfactory machine (the only precision process machine in the world which can be used in an operating room), and the first successful operation using these bone screws was at the University Hospital. Shimane University and Nano Corporation applied jointly for the patent.

## [Summary of the technology transfer]

## ●Technological Impact

All conditions met for medical use

35kg, 50 x 30 x 30cm, less than 50db

100V power supply, no surface level needed, placed on an ordinary wagon

washing and sterilization of the equipment possible, no oil for cutting necessary

an easy program that requires no training for doctors & nurses

development of peripheral equipment (special driver etc.).

## Market Impact

Inexpensive operation without expensive metal screws (e.g. from 300,000 yen to 100,000 yen for wrist joint fracture), continuation of advanced medical treatment even under a tight medical budget

(profitable with 1,000 domestic hospitals and 5,000 hospitals in the US & Europe after the purchase of the equipment for 10 million yen.)

## ● Social Impact

Can be used for the operation of patients for whom the conventional method is not possible (clinical tests at the University Hospital).

## ●Special Features of the Collaboration

The research task and its organization were drawn up based on a project plan with the following provisions:.

the Patients’ own biomechanical material to avoid side effects

Use of the best precision processing technology in the world

Small and medium-sized enterprises (1 billion yen), No overseas outflow

## Project Background

Nano Corporation, which was searching for a new field for its micro-factory machine, received a proposal from the Industry-University Cooperation Center, recognized a new innovative use, and decided on the joint development.

## Funding History

## Surgery with bone screws

taking bone fragment (spontaneous healing)

perfect biocompatibility no need for second surgery

1) 2004~2007 Shimane University, In-campus Priority Research Project

2) 2005 Shimane Industrial Development Foundation, Industry-Government-Academia Collaboration Test

3) 2005~2006 Ministry of Economy, Trade & Industry Community Rebirth Consortium Project

## I ntellectual property protection

Patent: Three domestic application

“Lathe, # 2005-059975”

“Chuck, #2005-051290”

Taylor-made (The optimal design)

“Equipment for bone connection, #2004-373719”

15 min at an operating theater

## Turning point in the Project

The research subject is strategically examined before the research begins.

The Cooperation Center chooses only the people who are truly necessary.

The users carry out all the integrated work on the practical tests.

All participants confirm that the objective of the research is not presenting an academic paper but making it fit for practical use within three years.
